Space Saver Right-Angle Shaft
The Croise motor, using a worm gear, provides space savings in the equipment layout with the right-angle shaft. The CSM Series is a 1st worm gear with a reduction ratio up to 1/60.
Quiet Operation
With the use of a worm gear, provides very smooth and quiet operation compared to other gear mechanisms. Also, the silent-type brake eliminates annoying metallic sound during suction.
Shock Resistance
The worm gear has a stronger tooth root than other gear mechanisms, providing superior shock resistance.
High Stopping Accuracy
Excellent positioning accuracy can be expected due to less backlash compared to other gear mechanisms.
